Nexa™ Start DS2

The Nexa™ Start DS2 is a further refined electronic blasting machine for the safe initiation of Nexa™ detonators. It consists of an energy source (battery), a voltage converter, a capacitor for energy accumulation, an electrode and pushbuttons to effect initiation. The electrical energy is converted to a powerful spark, which the electrode emits into the inside of the Nexa™ tube to initiate the shock-wave reaction.

The Nexa™ Start DS2 is powered by an ordinary 9 V alkaline battery that lasts for at least 1000 initiations. When the charging button is pressed, the capacitor is charged up to 2500 V. Pressing the firing button then emits a powerful spark that initiates the Nexa™ tube. Note that the charging button must be kept depressed throughout, or else the capacitor will be discharged over an internal resistance. It is easy to change the electrode.
